cellobiose dehydrogenase (quinone). Now known to be proteolytic product of EC 1.1.99.18, cellobiose dehydrogenase (acceptor)

[EC 1.1.5.1 created 1983, deleted 2002]

EC

1.2.1.1

Deleted entry:

glutathione-dependent formaldehyde dehydrogenase. This enzyme was classified on the basis of an incorrect reaction. It has been replaced by two enzymes, EC 1.1.1.284, S-(hydroxymethyl)glutathione dehydrogenase and EC 4.4.1.22, S-(hydroxymethyl)glutathione synthase

[EC 1.2.1.1 created 1961, modified 1982, modified 2002, deleted 2005]

EC

1.2.1.6

Deleted entry:

benzaldehyde dehydrogenase

[EC 1.2.1.6 created 1961, deleted 1965]

EC

1.2.1.40

Deleted entry:

3α,7α,12α-trihydroxycholestan-26-al 26-oxidoreductase. The activity is part of EC 1.14.13.15, cholestanetriol 26-monooxygenase

succinate dehydrogenase. The activity is included in EC 1.3.5.1, succinate dehydrogenase (quinone).

[EC 1.3.99.1 created 1961, deleted 2014]

EC

1.4.1.6

Deleted entry:

D-proline reductase. Now included with EC 1.21.4.1, D-proline reductase (dithiol)

[EC 1.4.1.6 created 1961, deleted 1982]

EC

1.4.1.22

Deleted entry:

ornithine cyclodeaminase. It was pointed out during the public-review process that there is no overall consumption of NAD+ during the reaction. As a result, transfer of the enzyme from EC 4.3.1.12 was not necessary and EC 1.4.1.22 was withdrawn before being made official

[EC 1.4.1.22 created 2006, deleted 2006]

EC

1.4.3.6

Deleted entry:

amine oxidase (copper-containing). This was classified on the basis of cofactor content rather than reaction catalysed and is now known to contain two distinct enzyme activities. It has been replaced by two enzymes, EC 1.4.3.21 (primary-amine oxidase) and EC 1.4.3.22 (diamine oxidase)

[EC 1.4.3.6 created 1961, modified 1983, modified 1989, deleted 2008]

EC

1.4.3.9

Deleted entry:

tyramine oxidase. Now included with EC 1.4.3.4 amine oxidase (flavin-containing)

[EC 1.4.3.9 created 1972, deleted 1984]

EC

1.4.3.18

Deleted entry:

cytokinin oxidase. Not approved as the enzyme was shown to be a dehydrogenase and not an oxidase (see EC 1.5.99.12, cytokinin dehydrogenase)

[EC 1.4.3.18 proposed 2000]

EC

1.5.1.4

Deleted entry:

dihydrofolate dehydrogenase. Now included with EC 1.5.1.3 dihydrofolate reductase

[EC 1.5.1.4 created 1961, deleted 1976]

EC

1.5.1.14

Deleted entry:

1,2-didehydropipecolate reductase. Now included with EC 1.5.1.21 Δ1-piperideine-2-carboxylate reductase

dihydropteridine reductase (NADH). Now included with EC 1.5.1.34, 6,7-dihydropteridine reductase

[EC 1.6.99.10 created 1978, deleted 1981]

EC

1.7.1.8

Deleted entry:

withdrawn in the light of further information on the acceptor

[EC 1.7.1.8 created 2002, deleted 2002]

EC

1.7.99.2

Deleted entry:

nitric-oxide reductase. Reaction may have been due to the combined action of EC 1.7.99.6 nitrous-oxide reductase and EC 1.7.99.7 nitric-oxide reductase

[EC 1.7.99.2 created 1961, modified 1976, deleted 1992]

EC

1.7.99.5

Deleted entry:

5,10-methylenetetrahydrofolate reductase (FADH2). Now included with EC 1.5.1.20, methylenetetrahydrofolate reductase [NAD(P)H]. Based on the reference, it had been thought that this was a separate enzyme from EC 1.5.1.20 but the reference upon which the entry was based has since been disproved
